I think a critical detail getting overlooked in the broader discussion of the changes brought by LLM AI is not quality but quantity. What I mean is, sure, AI isn't going to replace any one complete worker. There are vanishingly few jobs AI can 100% take over. But it can do 80% of a few jobs, 50% of more jobs, and 20% of a lot of jobs.
So at the company level, where you had to hire 100 workers to do something, now you only need 80, or 50, or 20. That's still individual people who are out of their entire job because AI did some or most of it, and their bosses consolidated the rest of the responsibilities onto the remaining workers.
Yeah, and the article is wrong, though only slightly. They seem to be confusing watts (power, energy over time) with Joules (energy, power times a duration of time). They give a passable definition in the beginning ("energy transfer"), but they seem to misunderstand what the "transfer" part means exactly.
If you find-replace all instances of "watt" with "watt-hour" after that starting definition, it would be more accurate. That's why I say it's only slightly wrong.
